CONTAINER HAVING BUNG Original Filed Jan. 16, 1928 Patented Dec. 3, 1929 PATENT OFFICE RICHARD L. PARISH, OF CHICAGO, ILLINOIS oonrnmnn HAVING VIBUNG Application filed January 16, 1928, Serial No. 247,163. Renewed May 27, 1929.

My invention relates to containers, such as metallic barrels, having holes therethrough for the reception and discharge of liquid or for furnishing air vents enabling such discharge and having suitable closures which are provided with flanges that lap annular seats surrounding the holes and which containers employ guards which have ring portions substantially coaxial with the holes and other portions lapping the closures to guard the same from undetectable removal.

Separately formed gaskets have hitherto been employed against which the ring .portions of the guards have been clamped to prevent leakage. It is the object of my invention to avoid the necessity of these separately formed gaskets. Broadly speaking, the invention resides in forming the ring portion and gasket in a unitary structure in which the gasket is normally inseparable from the ring portion. In carrying out my invention, the ring portion of the guard has an endless ridge which is initially hollow substantially throughout its length and which is integrally formed with the ring. This ridge surrounds the hole in the container and is entirely disposed, compressed and collapsed between the flange and its seat whereby said ring portion is itself constituted a sealing gasket.

The invention will be more fully explained by reference to the accompanying drawing showing the adaptation of my invention to the structure disclosed in Patent No. 1,633,555, issued to Francis RBurgess, June 21, 1927. In the drawing, Fig. 1 is a face view of a portion of a container wall with the preferred form of structure shown in assembly therewith, this figure being taken generally on line 11 of Fig. 2; Fig. 2 is a longitudinal sectional view with a portion of the plug shown in'elevation; Fig. 3 is a sectional view illustrating parts of the structure in separated relation; and Fig. 4 is a sectional View on line 4-4 of Fig. 2.

. The container, such as a metallic barrel, has one wall thereof, such as the sheet metal wall 1, formed with a depending rim 2 which surrounds a circular hole formed through this wall. An interiorly threaded bushing 3 is snugly received within this hole 'and is closely surrounded by said rim, this bushing being shown with an outwardly curled inner edge portion 4 which grips the inner edge of said rim 2 and a circumscribing flange 5 which is tightly seated upon the wall 1, this flange desirably lapping this wall on the exterior of the container. The closure plug 6 is screwed within'the bushing 3 and is formed with a circumscribing flange 7 which laps the flange 5 and wall 1. The outer end of the plug is formed with two tool engaging formations, one in the form of an enlargement 8 which is of hexagonal 0r polygonal exterior contour, and the other in the form of a recess 9 extending through the enlargement 8, this recess being of square or other contour to receive a wrench having a plug formation snugly receivable within and corresponding in shape to said recess.

The sealing device or guard illustrated is in the form of a hood of sheet metal comprising a body or skirt portion 10 that is inclusive of a ring portion 11 which is confined between the flanges 5 and 7, Said 75. hood also includes a cap portion 12 which is not initially assembled or fully assembled with the body or skirt portion 10, the closure r plug being t1 htly applied before the cap'is finally assem led to enclose the plug pors0 1 tions 7, 8. The rims of the cap portion 12 and skirt portion 10 may be clinched together as illustrated at 13. All of the plug upon the exterior of the container is thoroughly guarded from undetectable access by the construction described.

The entire closure illustrated for the hole in the container wall includes the permanently applied bushing 3 and the plug 6 removably screwed within the bushing 3. Hitherso to, a separately formed gasket was interposed between the ring portion 11 of the guard and the underlying flange 5, this flange constituting an annular seat substantially coaxial with the hole in the wall. I eliminate an added gasket by forming one or more endless ridges 14 in and integral with the sheet metal ring portion 11 of the guard, each ridge surrounding the hole and being initially hollow substantially throughout its 0 length, the ridges being in sinuous relation, in cross section, if a number of them are employed, Fig. 3. .The ridges are entirely disposed, compressed and collapsed between the ange 7 and the flange or seat 5, Fig. 2, whereby said sheet metal ring portion 11 is also constituted a sealing gasket. The gasket information 14, being integral with the ring 11, is maintained in fixed relation to this ring and is, therefore, always accurately positioned with respect thereto and the closure portions 5 and 7 between which said ridges are clamped.

Changes maybe made without departing from the invention.

Having thus described my invention, I claim;

1. In a sput construction for a container having a hole thru a wall thereof, a flanged bushing adapted to be inserted in said hole,

a flanged closure plug cooperating with said I bushing, and a guard having a rmg portion ofxsheet metal adapted .to. be clamped be tween said flanges, said ring portion having an initially hollow ridge substantially concentric to the said opening adapted to be compressed as the plug is inserted, thereby to serve both as a sealing means and gasket element. f

2. In a sput constructionfor a'container having a hole thru .a wall thereof, a, flanged bushing adapted to be inserted in said hole, a flanged closure plug cooperating with said bushing, and a guard having a ring portion of sheet metal adapted to be clamped between said flanges, said ring portion having a plurality of initially hollow= rid es substantiallyconcentric to the said opening adapted to be compressed as the plug is inserted, thereby to serve both as a sealing means and gasket element.

3. In a sput construction for a container having a hole thru a wall thereof, a flanged bushing adapted to be iifserted'inisaid hole,

a flanged closure plu cooperating with said bushing, and a guar having a ring portion of sheet metal adapted to be clamped between said' flanges, said ring portion having -a plurality of initially hollow concentric ridges integrally formed in said sheet metal ring and, substantially concentric to the said opening adapted to be compresed as the plug is inserted, thereby to serve both as a sealing means and gasket element.

In witness whereof, I hereunto subscribe my name.
